• Extron XTP DTP 24 shielded twisted pair cable is strongly recommended for
optimal performance
• Bidirectional RS-232 and IR pass-through for AV device control — Bidirectional
RS-232 control and IR signals can be transmitted alongside the video signal over
the DTP connection, allowing the remote device to be controlled without the need
for additional cabling. Bidirectional control extension eliminates the need for control
system wiring to remote devices.
• Remote powering of DTP receiver — The Annotator 300 can provide remote
power to a DTP receiver over the twisted pair connection, eliminating the need for a
separate power supply at the remote unit.
• Compatible with all DTP 230 and DTP 330 Series receivers, and DTP-enabled
products — Enables mixing and matching with desktop and wallplate receivers, as
well as other DTP-enabled products to meet application requirements.
• DTP output is compatible with HDBaseT-enabled devices — The DTP output
can be configured to send video and embedded audio, plus bidirectional RS-232 and
IR signals to an HDBaseT-enabled display.
• Auto-switching between inputs — Auto-switching allows for simple, unmanaged
installation in locations such as in a lectern or under a conference table. When
multiple inputs are active, the switching priority is configurable.
• Auto Input Format Detection — For the universal analog video input, the Annotator
300 detects the incoming signal format, automatically reconfiguring itself to provide
the appropriate decoding and signal processing. This feature can reduce the number
of required outputs for a matrix switcher, lowering system cost while improving
manageability.
• Selectable output rates from 640x480 to 1920x1200, including HDTV 1080p/60
and 2K — Available output rates include computer-video up to 1920x1200, HDTV
rates up to 1080p/60, and 2K.
• Advanced scaling engine with 30-bit processing and 1080i deinterlacing —
Image scaling and video format conversion are performed at 30-bit precision for
enhanced color accuracy and picture detail. High performance deinterlacing of 1080i
signals from HD sources delivers optimized image quality.
• Key Minder continuously verifies HDCP compliance for quick, reliable
switching — Key Minder authenticates and maintains continuous HDCP encryption
between input and output devices to ensure quick and reliable switching in
professional AV environments, while enabling simultaneous distribution of a single
source signal to one or more displays.
• EDID Minder automatically manages EDID communication between
connected devices — EDID Minder ensures that all sources power up properly and
reliably output content for display.
• SpeedSwitch Technology provides exceptional switching speed for HDCP-
encrypted content
• Aspect ratio control — The aspect ratio of the video output can be controlled by
selecting a FILL mode, which provides a full screen output, or a FOLLOW mode,
which preserves the original aspect ratio of the input signal.
• HDCP authentication and signal presence confirmation — Provides real-time
verification of HDCP status for each digital video input and output. This allows for
easy signal and HDCP verification through RS-232 or Ethernet, providing valuable
feedback to a system operator or helpdesk support staff.
